A Comet Up Close and Personal

In 2004, the Rosetta spacecraft was launched by the European Space Agency (ESA) with the goal of landing a probe on a comet. On November 12, 2014, some 3907 days later, the Philae lander was deployed from Rosetta and landed on comet 67P/Churyumov-Gerasimenko. This marks the first time that a probe has been landed on a comet’s surface. Here are some of the breathtaking photographs this mission has produced. Images via nasa.gov.
